Re: bandit slayer problem
It does a little damage, just not much. It was left out of the game for that reason probably.
You may be able to increase this damage, I have not tried myself.
Open FE, scroll down ro CAugmentationDef,
Single click the plus sign,
Double click 11385, single click plus sign in new window,
Single click the plus sign DFA5CC9C-Added Damage,
Change that value to something higher.
Apply changes and Save Mods Run Fable.
See if that makes the effect of flourishing do more damage.
Good luck
